Answer:
The water quality is deteriorated as there is depletion in Oxygen O₂.
Yes, the activity of the yeast has precluded the usage of the water
Explanation:
Here, we note that the addition of more or fewer drops of Reagent D sodium hydroxide (NaOH) is required to get the same blue color as in Phase 1 where no yeast is added indicates the level of O₂ in the water as the amount of O₂ concentration in the solution is directly proportional to the amount of Reagent D required to reach blue, meaning the O₂ is depleted.
When less sodium hydroxide is required to turn blue we have depleted sodium hydroxide in the solution that is the yeast added in Phases 2 or 3 of the experiment, consume O₂
Eutrophication is the enrichment of a body of water with nutrients that results in a change in the ecosystem such as: algae production, oxygen depletion and other results that diminishes the water usage.
<u>Answer:
</u>
Yes, it is true that researchers looking for cause-and-effect relationships will most often use epidemiological studies.
<u>Explanation:
</u>
- The functioning pattern of the epidemiological study characterizes its method and manner of probing and investigating to the depth of the issue in order to find the root cause of the problem that has been encountered.
- Thus, to probe for a cause and effect relationship, an epidemiological study would prove to be highly beneficial as it would put to use the right methods of investigation.
Answer:
Large industrial prisons
Explanation:Large industrial prisons - it is considered to be the military complex that is under by private agencies for profit. The contract of Large industrial prisons is held to provide the cheap labor at the prison, surveillance technology, food services or any other facilities at prison.
This is considered to be the new trend in some parts of America in which prison is handled by private agencies to make some profit.
Answer:
in the center of the atom, surrounded by the electron cloud
Explanation:
The nucleus is found at the center of the atom. It houses the neutrons and protons.
If Mike intends to draw a proper model of the atom, then he must draw the nucleus at the center of the model surrounded by the electron cloud. This is in accordance with Rutherford's nuclear theory of the atom.
A main goal of the progressives was to improve this problem is to change other people
